Happy New Year everyone! I suggest we start 4.0.M3 release vote in a week or two. While we are behind on the major features (like aggregates in ObjectSelect), we have a bunch of other important things (like Java 8 support, bug fixes, etc) [1]. A few downstream frameworks that I am developing (link-move, bootique) require those features and bugfixes and currently have to rely on non-official builds.
So unless there are objections, I am going to initiate the vote soon. I also suggest that we hold on with any disruptive commits to master until then. Thanks, Andrus [1] https://github.com/apache/cayenne/blob/master/docs/doc/src/main/resources/RELEASE-NOTES.txt
